Marble track - gauss cannon (remixed to fit smaller magnets)

Remixed the model to house two, 5 mm thick, 10 mm diameter magnets. I made a quick and dirty remix using eSlicer which cannot export negative volumes into STL format, so the uploaded 3MF file needs to be opened in eSlicer or a compatible fork of eSlicer.

The two magnets I used gives the marble a proper shove but unfortunately they are so strong that I am unable to reload the cannon by pure hand.
